One Size Does Not Fit All for Parent-Mediated Autism Interventions: A Randomized Clinical Trial
Teach parents responsive language first; moms learn it faster and use it more, especially if they start with few skills and few autism-like traits.
01Research in Context
What this study did
Roberts et al. (2023) split mothers of toddlers with autism into two groups. One group learned responsive language tips: wait, follow the child’s lead, and expand. The other group learned directive tips: prompt, cue, and direct the child.
Coaches visited each family at home for six weeks. Moms were filmed before and after so researchers could count how often they used the new moves.
What they found
Moms taught the responsive way used the moves far more often than moms taught the directive way. The gap was biggest for mothers who started with few language moves and who showed fewer autism-like traits themselves.
How this fits with other research
Jones et al. (2024) ran a nearly identical trial but saw the opposite result: directive moves led to better child language. The key difference is the outcome. Roberts looked at whether moms learned the moves; Jones looked at whether kids talked more.
Brian et al. (2026) add another layer. They found toddlers with the lowest baseline language sparked the biggest caregiver gains, matching Roberts’ finding that moms who start low catch up fastest.
Pacia et al. (2021) reviewed eight parent programs and saw both styles work, so picking the style that fits the parent may matter more than picking one "best" style.
Why it matters
When you coach families, start with responsive moves unless data say otherwise. Watch two things: how many language moves the parent already uses, and any autism-like traits the parent shows. If both are low, add extra practice and feedback before moving to directive moves.

03Original abstract
Coaching parents to use language facilitation strategies improves long-term language outcomes for autistic children. To optimize parent-mediated interventions, more studies need to explore factors that influence parents’ learning. The current study involved 119 autistic children (18–48 months) and their biological mothers enrolled in a single-site, factorial randomized clinical trial. Mothers were taught to use one of two types of language facilitation strategies (responsive or directive) during eight weekly, hour-long instructional sessions. We explored the impact of (a) type of language facilitation strategy, (b) maternal Broad Autism Phenotype (BAP; subclinical traits of ASD), and (c) pre-intervention strategy use on mothers’ outcomes measured immediately and 3-months after intervention sessions. At post-intervention, mothers who learned responsive strategies demonstrated significantly greater use of taught strategies than mothers who learned directive strategies (d=0.90, 95% CI=[0.47, 1.32]). Mothers’ use of taught strategies did not differ by BAP status. However, a significant two-way interaction was found between pre-intervention strategy use and BAP status on taught strategy use (F(1,107)=6.04, p=0.016, ΔR2=0.053). Findings suggest that strategy type, maternal BAP status, and pre-intervention strategy use may be important factors to consider in order to individualize parent-mediated interventions.
